I travel very rarely. Not for work in many years. I have not given any consideration to a travel guitar, but I did buy an ergonomic guitar that is also smaller. Here is my experience:
I make a trip annually for a 5-day stay at a resort. I have taken my guitar each of these trips so I can sit outside or in the room and play. I have taken my PRS most of the time, but last trip, I took the Strandberg. I have taken the effects processor on two or three occasions, but also take a headphone amp for portability and quiet. I can set volume to play quietly and the rooms are isolated enough that I do not think anyone can hear me. I have taken the speaker cabinet once, but this is pretty large to take with.
However, this past Christmas, I took the Strandberg to mom’s house in case I had time to play. I was invited over to a neighbors and had my first experience playing with others. I immediately wished I had my regular setup. We tried to fit my guitar into the neighbor’s clean amp he uses with his violin, but ended up just using my laptop with a small speaker I like for portable practice. Next year I will probably take the whole setup.
